P'u tzu was an animal native to Pai. It mostly resembled a tentacled rabbit with large horny growths. The Pai saw this animal as a delicacy, especially its gland, where it stores all the toxins it would ordinarily release into its urine. When braised lightly with peppers it becomes piquant. The fresher the kill the greater maturity of its flavor. (TNG novel: Dragon's Honor)
